We look at the division of 67692 by 66 
The aim is to understand the frequency of 66 in 67692.

On to step 1:
The number 66 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 66

Advancing to step 2:
If we divide 67 by 66, we get 1 and a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
If we take 66 away from 67, we end up with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 66

Step 3:
The number 66 fits into 16 0 times, leaving a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 16, we end up with 16.
Append the next digit (9) from the dividend to 16 and continue with: 169 / 66

Step 4:
The number 66 fits into 169 2 times, leaving a remainder of 37.
Write down 2 as next digit of the result. 
Result so far: 102.0
Subtract 132 from 169 to get 37.
Fetch the next digit (2) from the dividend, attach it to 37 and continue: 372 / 66

Moving on to step 5:
The number 66 fits into 372 5 times, leaving a remainder of 42.
Put 5 as the next digit of the answer. 
Result so far: 1025.0
If we subtract 330 from 372, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 6:
When dividing 420 by 66, we get 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 1025.6
Subtracting 396 from 420 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 7:
When dividing 240 by 66, we get 3 with a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 1025.63
If we take 198 away from 240, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 8:
420 divided by 66 is 6 with a remainder of 24.
The next digit of our result is 6. 
Result so far: 1025.636
Subtract 396 from 420 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 9:
66 goes into 240 3 times with a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 1025.6363
Deduct 198 from 240 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 10:
If we divide 420 by 66, we get 6 and a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 1025.63636
The remainder is 24 after subtracting 396 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 11:
When dividing 240 by 66, we get 3 with a remainder of 42.
The next digit of our result is 3. 
Result so far: 1025.636363
If we take 198 away from 240, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 12:
66 can be fit into 420 6 times, resulting in a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 1025.6363636
If we take 396 away from 420, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 13:
If we divide 240 by 66, we get 3 and a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 1025.63636363
Subtracting 198 from 240 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The quotient of the division is 1025.63636363, and the remainder is 4.2e-08.
